Paul Riseborough 89142f1c5f AP_NavEKF: Prevent inadvertent use of DCM roll and pitch estimates.
the use of roll and pitch from the AHRS object is bad because that object could be returning estimates from the backup DCM algorithm.

Andrzej Zaborowski 132cdc4916 Motors: Use _motor_to_channel_map in tricopter consistently.
In AP_MotorsTri.cpp the AP_MOTORS_MOT_1, _2 and _4 constants are
always mapped to actual output channels through _motor_to_channel_map
while the _CH_TRI_YAW is not, but there were a few inconsistencies
in this that could lead to things like PWM min and max values being
set on wrong channels.

It looks like all in all _motor_to_channel_map being in PROGMEM
probably doesn't help save memory and I'm not sure how useful it is
in the first place but regardless the usage should be consistent.

Tom Pittenger 9ecbd0e30f AP_L1_Control: fixed uTurn-wobble
When performing a u-turn in AUTO (waypoints are 180deg turn from each other) sometimes the aircraft can't decide to turn left or right and wobbled back and forth a couple times. There was existing code to solve this but it was not executing all the time like when in LOITER mode. Frankly, I don't understand the criteria that was required to make it execute and i suspect there is still a gremlin in that logic but just executing the check all the time makes prevents the wobble behavior.

Paul Riseborough 10f050c53b AP_NavEKF: Prevent baro drift causing toilet bowling
The magnetic field states are reset once at 1.5 metres and again at 5 metres. This height check was using the height at the first arm event as the reference. In the situation where there is baro drift and extgended time between the first arm event and flight, this can cause the magnetic field state to be reset when on the ground. If this happens when flying off a metallic surface, the resultant heading errors can cause sever toilet bowling.
